Disable Time Machine Local Backups in Mac OS X Lion & Mountain Lion

Submitted by Janak on Thu, 01/31/2013 - 14:29

OSX Lion introduced "Local Backups" or "Snapshots". This feature happens to kick in when the TimeMachine drive is an external one. This is great because TimeMachine can still maintain a backup whilst the external drive is unplugged. However, for those of us with 128GB (or smaller) SSDs it eats up the precious free space.

If you happen to be running out of space, here is how you can disable this feature (without disabling TimeMachine completely)

Disable Local Backup on Lion and Mountain Lion

Open up Terminal and type

sudo tmutil disablelocal

Enter the admin password and you will have more of the super fast SSD free space.

Enable Local Backup on Lion and Mountain Lion

Open up Terminal and type

sudo tmutil enablelocal

Enter the admin password and you will have Local Backups back where they belong.
